AI Article Synopsis
- The study presents a new method to analyze how reverberation affects auditory brainstem responses to speech, focusing on the impact of self- and overlap-masking in different room settings.
- ABR measurements were taken in three environments: anechoic, mild reverberation, and severe reverberation, revealing that severe reverberation led to weaker responses and longer latencies compared to the other conditions.
- Results indicated that while mild reverberation produced stronger responses and shorter latencies than anechoic conditions—likely due to early reflections—these differences were statistically significant in only one of six measured ABR responses.
Article Abstract
This study introduces an improved method to investigate the effects of reverberation using the speech-evoked auditory brainstem response (ABR) that more realistically captures the influence of self- and overlap-masking induced by room reverberation. Speech-evoked ABR was measured under three acoustic scenarios: anechoic, mild reverberation with dominance of early reflections, and severe reverberation with dominance of late reverberation. Responses were significantly weaker and had longer latencies with severe reverberation relative to anechoic and mild reverberation. Although larger responses and shorter latencies were observed with mild reverberation than anechoic, possibly due to early reflections, these reached significance in only one of six ABR response measures.
